Cigarette Beetle or Black Carpet Beetle

6244 Found this scrambling under my bed when I was doing an inspection. I did crush it a little, hence the break and ooze at the bottom. Scared it’s a bed bug, but it doesn’t look like bed bug pictures I found. From Toronto, ON

Number 6244 – This beetle could be either in the family Anobiidae (such as the cigarette beetle) or Dermestidae (such as the black carpet beetle); a clearer view of its antennae would be helpful. Definitely not a bed bug!

Death-Watch Beetle

6231 These little guys recently showed up in the last week (end of May) in my basement. I noticed them on the floor, ceiling, around the windows and around the door to the mechanical room where we brought in some wood from the garage in the winter. The weather lately has been mild and wet, with temperatures fluctuating.

Number 6231 – This appears to be a death-watch beetle in the genus Ptilinus (Coleoptera: Anobiidae); see Click here for some images. These likely came in as larvae within the firewood; their larvae bore in the wood of several hardwood species, but are not known to attack wooden structures.

Foreign Grain Beetle

6226 I took photos of this insect on my bed today (May 31st, 2018). Lately the weather has felt like summer. I’ve started noticing them about a week ago and mainly on and in my bed, maybe 1 or 2 at a time. As I would start falling asleep, I would wake up and find one on my pillow. So far I have no bites, hives or itchy spots. I removed my bed sheets and there are no bug infestations or blood stains. Yesterday I just kept seeing them in almost every room of the house (floors, walls, ceilings, bedding, etc.). They are tiny and much smaller than an apple seed. All the ones I’ve caught look the same. I’m wondering if they are an early stage bed bug. How do I get rid of them? From Ottawa, Ontario

Number 6226 – This appears to be a foreign grain beetle, Ahasverus advena (Coleoptera: Silvanidae). Sometimes also called new house beetles or plaster beetles, they feed primarily on mould/mould spores found in humid/damp environments. Reducing indoor relative humidity levels should control them. Click here for more detailed information
